SYLVESTER ROBINSON AND JAMES A. SAFFER, OF EMPORIA, KANSAS.

RIDING-WHEEL ROAD-SCRAPER.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed July 15, 1908. Serial No. 443,665.

To all whom it may concern:

Be it known that we, SYLVESTER ROBIN- SON and JAMES A. Sarrnn, citizensof the United States, residing at Emporia, in the county of Lyon andState of Kansas, have invented certain new and useful Improvements inRiding-'Wheel Road-Scrapers; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in riding wheelroad scrapers and rock gathering apparatus and comprises various detailsof construction, combinations and arrangements of parts which will behereinafter fully described and then specifically defined in theappended claims.

We illustrate our invention in the accompanying drawings, in whichFigure 1 is a side elevation of the apparatus with one wheel removed.Fig. 2 is a top plan View. Fig. 3 is a sectional view through the frameof the apparatus showing parts in rear elevation. Fig. 4 is an enlargeddetail in perspective of one of the braces of the apparatus. Fig. 5 is adetail View of a scoop supporting bar. Fig. 6 is a sectional Viewthrough the rock gathering pan, and Fig. 7 is a top plan View of therock gathering pan.

Reference now being had to the details of the drawings by letter, Adesignates the frame of the apparatus to which the tongue A is connectedand B is the axle upon which the wheels B are mounted and C is a seatmounted upon the rear end of said tongue or pole.

D designates a shaft which is journaled in suitable bearings upon theframe, and E and E designate two operating levers mounted upon the shaftD. One of said levers E is fixed to the shaft D and carries a pawl Fadapted to engage the teeth of the segment F which is mounted upon theframe of the apparatus. By swinging the lever E forward or backward, theshaft D may be rocked. Crank arms G are fixed to the ends of said shaftD and links G pivotally connected at their upper ends to said arms andat their lower ends to the strap H which is fastened to the scoop H.

Mounted upon the frame of the apparatus and in the rear of the axle is arock shaft I having a crank arm I fixed thereto, and J designates a barhaving adjustable pivotal connections between the arm I and the lever Eafiording means whereby the shaft 1 may be rocked. Fixed to the shaft 1are the forked members having the arms K and K, the latter of whichcarries a pivotal pin N connected to the bar 9, the lower end of whichbar is pivotally connected at Q to the strap Q, near the rear end of thescoop. The arm K, a detail of which is shown in Fig. 4 of the drawings,has a slot K at one end in which the bar 0 has a slight play.

R designates a hinged back to said scoop mounted upon the pivot pin R,and R designates a chain having branching ends R as shown clearly inFig. 3 of the drawings, each of which is pivotally connected to a latchlever K Catches R are mounted upon the sides of the scoop, as shown inFig. 1 of the drawings, and each is adapted to be engaged by a latch barK. The chain R is preferably fastened to the seat of the apparatus asshown, whereby it will be within convenient reach when it is desired totilt the scoop.

It will be noted that the lower end of the bar 0 has an elongated slot 0in the end thereof which engages the strap Q, upon the scoop, thusallowing a slight play in providing means whereby the scoop may beconveniently tilted forward or rearward.

Referring to Figs. 6 and 7 of the drawings will be seen a slightmodification of the scoop in which a device is arranged for carryingrock in which, instead of having a closed bottom as shown in Fig. 2 ofthe drawings, a series of bars T is provided, said bars being arrangedin pairs and each .pair made from a single piece of metal, and Tdesignate crosspieces, preferably of metal, which are bent uponthemselves and provided with apertures through which the bars pass.

thrown rearward which will cause the rear end of the scoop to be raised.If it is desired to tilt the forward end of the scoop upward in theevent of dumping, the lever E is swung rearward and, if it is desired toraise the scoop so that it will rest horizontally a distance from theground, both levers may be simultaneously moved which will cause thescoop tobe raised up so that its upper edge will be adjacent to theframe .of the apparatus. As the lever E is thrown rearward, the forkedmember having the arms K and K" will cause the scoop to be given aslight forwardmovement incident to'the fulcruming of the bar 0 over theend of the recess K in'the end of the arm K.

When it is desired to dump the scoop, the operator by pulling upon thechain may release the latches and allow the inclinedgate to swinguponits pivots. As the gateswings down, it will automatically lock in aclosed relation. When it is desired to utilize the rock carrying pan,the scoop may be readily detached from the bars Gr and 0 and the form ofpan shown in Figs. '6 and 7 substituted therefor.

What we claim tobe new is 1. A riding wheel scraper comprising, incombination with a frame, an axle and wheels mounted thereon, a shaft'journaled upon said frame, a lever fixed to said shaft, a scoop, crankarms fixed to the shaft and having pivotal link connections with thefront end of-said scoop, a second shaft journaled upon the frame,aforked member fixed to said second shaft, a link pivotally connectedtoone of the arms of said member and to said scoop, said link beingfulcrumed in the recessed end of the other arm of the member, a secondlever pivotally mounted upon said first mentioned shaft,a'bar connectingsaid second shaft and lever upon the crank shaft,as set forth.

:2. A riding wheel scraper comprising, in combination with a frame, anaxle and wheels mounted thereon, a shaft journaled upon saidframe,'a-lever fixed to said shaft, a scoop, crank arms fixed 'tothe-shaft and having vpivotal link connections with the front end ofsaid scoop, a second shaft journaled upon the frame, a forked memberfixed to said second shaft, a link pivotally connected to one of thearms of-said memsaid-scoop, a latch mounted upon said gate,

and a chain connected to said latch, as set forth.

3. In combination with a frame, an axle thereon, wheel's upon said axle,a shaft journaled in suitable bearings upon the frame, crankarms fixedto said shaft, a lever secured to the latter, a scoop, link connectionsbetween said scoopand crank arm, a toothed segment, a pawl carried bythe lever and adapted to engage'the teeth of the segment,
